How many minutes per week cold exposure is sufficient

According to Andrew Huberman, a good guideline for deliberate cold exposure is approximately 11 minutes total per week. This duration should be spread across multiple sessions, ideally divided into two to four sessions of two to three minutes each. This threshold is mainly suggested for improvements in metabolism and maintaining consistency without overdoing it. If you find 11 minutes too easy, you can increase either the exposure duration or frequency while ensuring you do it safely 1.
